poMMo (pommo.org) - Mailing list management and throttling

Someone, *PLEASE* create an extension that ties the Lussumo user database in with poMMo. It looks like an extremely nice PHP-based mailing list manager and has all the things people have always been asking for such as bandwidth/emails volume throttling (even on a per domain basis) and other things I can't currently remember people demanding.

Alternatively, someone else give me a good reason why this software isn't great

I've been meaning to try out Pommo. Just read here (ModCMS forums, Jan 07) that Pommo might be switching over from phpmailer to http://www.swiftmailer.org/. The list of features for Swift is impressive (see link).

Swift is a fully OOP library for sending e-mails from PHP websites and applications. It does not rely on PHP's native mail() function which is known for using high server resources when sending multiple emails. Instead, Swift communicates directly with an SMTP server or a MTA binary to send mail quickly and efficiently.
